How to spoof your IP address using NMAP in Windows
Networking 101: How to spoof your IP address using NMAP in Windows Sometimes when building firewall rules in a big network it's difficult to tell what will happen to routing and inside a firewall just by looking at the rules. In many cases somebody wants a server with some IP address to talk to another server somewhere on the network. The best thing to do is traceroute, or telnet to the service ports from the source host and see what the firewall does with the traffic. Does it ever see the packet? If so does it allow or block it? This becomes more difficult when you don't have access to the source host, and/or the people in charge of it are unwilling/unable to run a trace. As in maybe they don't know how or just don't respond to your questions in time. If you try to explain 'telnetting to a port' it can confuse a lot of DBA's :-O So here's the next best thing - you can try it yourself, but "spoof" the source IP address of the reque
